Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than ...

Electronically-variable capacitors, whether used for T&M or in an end circuit, usually have a maximum capacitance of a few hundred picofarads, and a limited adjustment range. This Design Idea ...

There’s one component which used to be ubiquitous in every experimenter’s junk box, but nowadays unless you happen to be a radio amateur the chances are you may not have seen one in a long time, if ...

Emerging applications like 5G communications and evolving automotive requirements such as for advanced driver-assistance systems (ADAS), autonomous driving, and on-board chargers for electric vehicles ...

Single-cell EC capacitors can reach 50,000 + farads. Daniel O'Brien, North American Capacitor Corp., Greencastle, Ind. All capacitors consist of two metallic electrode plates separated by an ...
